The inadequate production statistical database has been an important drawback for the formulation of strategic development plans. The hatchery is certified by NFDB. India has already drawn up a strategic plan for doubling freshwater aquaculture production through increases in productivity and area. Greater susceptibility of the species to Argulus infection over catla and mrigal in polyculture systems is another common problem, especially at higher stocking densities. In extensive systems, with a targeted production level of 2-3 tonnes/ha, the cost of production is about USD 0.30/kg, while the costs increase to USD 0.5-0.6/kg in semi-intensive culture, where the targeted production is 4-8 tonnes/ha. Since rohu forms an important component of the carp polyculture system, it can be expected that there will be a two-fold increase in its production in India by 2015. The depth of water in the breeding tank is maintained at up to 1.5 m, based on the broodstock density; 3-5 kg broodstock/m³ is usually recommended. 1★ Healthy rohu fingerlings were procured from a government fish seed hatchery in Lahore and acclimatized under laboratory conditions for two weeks prior to this feeding trial. Rohu is a highly preferred carp and fetches comparatively high market prices. A large share of the production still comes from extensive farming involving stocking and fertilisation as the inputs and achieving more modest production levels of 1-2 tonnes/ha/yr. Meena Kumary, assistant director at Neyyar National Fish Seed Farm, says the hatchery focuses on freshwater fishes such as catla, rohu, mrigal, … Pre-stocking nursery pond preparation should include the removal of aquatic weeds and predatory fish, followed by liming and fertilisation with organic manures and inorganic fertilisers. Supplementary feed constitutes over 50 per cent of the total input cost in carp polyculture; therefore, judicious feed management is of prime importance for enhancing profits. Up to 10 percent of the cichlid fish in Ghana’s Lake Bosomtwe can be traced to escapees from a short-lived illegal Nile tilapia farm, according to new research.

However, locally-produced fresh fish fetches about one and half times higher market price than iced fish. Experimental fish (8.503 ± 0.009 g) were randomly distributed into three groups and kept in well-aerated glass aquaria filled with 50 L of water (60 fingerlings/group). We have the biggest fish hatchery in India where artificial breeding is done under controlled conditions so as to produce healthy species. Other factors are expected to influence further growth in the farming of Indian major carps, including: The official production figures often do not represent a true picture, due to the lack of appropriate and uniform data collection mechanisms. The optimum temperature for spawning is 22-31 °C. Application of the principles of Article 9 of the FAO Code of Conduct for Responsible Fisheries would be appropriate. In nature, spawning occurs in the shallow and marginal areas of flooded rivers. The Chinese circular hatchery is the most common system used for seed production. Though the beneficial effects of pre-stocking nursery pond preparation are well-established, some of these activities are often ignored by the farmers, resulting in poor fry survival. Karnal: Bultana: 10: 1-Rohu 2-Catla 3-Mirgal: 3. Rearing fingerlingsNursery phase Three day old hatchlings, measuring about 6 mm, are reared up to fry of 20-25 mm in small earthen nursery ponds of 0.02-0.1 ha. ★★★★★ 5★ Rohu is one of the most popular & spectacular species of 'freshwater shark'. While induced breeding through hypophysation has been the common practice since the development of the technology in 1957, several synthetic commercial formulations of purified salmon gonadotropin and dopamine antagonists such as Ovaprim, Ovatide and Wova-FH have also been successfully used in recent years. The higher price of commercial feeds has been forcing farmers to resort to the conventional bran-oil cake mixture, usually supplied in dough form, thus leading to wastage and deterioration of water quality.
